J.J. Kroes Facilities for the import of bulk materials
Literature survey, Report 2004.TT.6871, Transport Engineering and Logistics.

Bulk handling is done in many ports all over the world. In the past, a considerable increase of scales in bulk export terminals has been realised (sometimes up to 10.000 tons/hour per loading machine). Some import terminals for bulk materials have realised new facilities with larger handling capacities as well and due to the ongoing growth for some bulk commodities it is expected that new facilities are to be planned in many bulk importing ports in the coming 5-10 years.

The research in this assignment covers the following topics:
This report consists of a study of facilities for the import of bulk materials.

The report includes a summary of the world wide most important ports/terminals, indicating size and dominant commodities. The summary is based on an older list by Ocean Shipping Consultants Limited "Bulk port and trade development: The Investment Outlook", published 1996. The information for this list is updated where possible and is organized in two tables. One table focuses on the achieved throughput of a port or terminal, the other on the capacity for handling and storage. The tables are located in appendix I of the report. The setup of the tables is shown here, for a further detailed explanation see chapter 2 of the report.

This report also includes a summary of applied systems and equipment for handling and storage of dry bulk materials and some characteristic information about this equipment. The basic setup for this summary is a picture of the equipment, with information about capacities and other data next to it. This summary is located in appendix II of the report. An example is shown here:

A description of key material characteristics is given, pertaining to the specific weight, angle of repose, lump size, etc. The information is based on manuals from the conveying industry, and the common materials have been selected on basis of recurrence and the advice of ing. M.J. Willekes. A list of common dry bulk materials and their key characteristics is given in appendix III. This list is as shown here:

Finally, an analysis of trends in the dry bulk material handling import facilities is made. This analysis is made from extensive literature research in journals and websites concerning dry bulk handling and related issues.

The main trends are:
